由于人类进化过程中食物种类的变化带来咀嚼器官功能退化、颌骨有缩小现象,因而造成颌骨齿槽突长度的不协调。下颌第三磨牙(智齿)位于牙列最后,也是最晚萌出的牙齿,正常萌出过程中其颌面及远中软组织退缩较迟,或因第三磨牙与下颌之间位置不足,导致程度不同的阻生。现将下颌阻生第三磨牙拔除术的护理总结如下。1临床资料1.1一般资料门诊对35例下颌第三磨牙阻生病人行拔除术,其中男16例,女19例,年龄17岁~42岁, Due to the changes of food species in human evolution, the function of chewing organs deteriorates and the jaws shrink. As a result, the incoordination of the length of the alveolar process of the jaw is caused. The third mandibular molars (wisdom teeth) are located in the last and last eruptions of the dentition. The soft tissues of the maxillofacial and distal soft tissues retreat later in the normal eruption process, or due to the lack of position between the third molars and the mandible, resulting in different degrees Impacted. Now impacted third mandibular mandibular extraction of care is summarized as follows. 1 Clinical data 1.1 General Information Out-patient 35 cases of mandibular third molars impacted patients with extubation, including 16 males and 19 females, aged 17 to 42 years old,
